95-14-01 GLASER-DIRKS FLUGZEUGBAU GMBH: Amendment 39-9293; Docket No. 92-CE- 21-AD.
Applicability: Model DG-100 sailplanes (all serial numbers) that are equipped with the main L4 fitting of the all flying tailplane, certificated in any category.
NOTE 1: This AD applies to each sailplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For sailplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must use the authority provided in paragraph (d) of this AD to request approval from the FAA. This approval may address either no action, if the current configuration eliminates the unsafe condition, or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration onthe unsafe condition addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any sailplane from the applicability of this AD.
Compliance: Required within the next 100 hours time-in-service after the effective date of this AD, unless already accomplished.
To prevent loss of control of the sailplane caused by failure of the tailplane main fitting, accomplish the following:
(a) Inspect the tailplane main fitting to ensure that the welding covers the entire wall thickness of the fitting in accordance with the instructions in paragraph 3 of the Enclosure to Technical Note (TN) 301/15, which is a supplement to Glaser-Dirks TN 301/15, dated July 7, 1989.
(b) If the welding does not cover the entire wall thickness of the fitting, prior to further flight, modify the tailplane main fitting in accordance with instructions in paragraph 4 of the Enclosure to TN 301/15, which is a supplement to Glaser-Dirks TN 301/15, dated July 7, 1989.
NOTE 2: The service information specifies inspection and possible modification for the Model DG-100 Elan sailplanes, as well as the Model DG-100 sailplanes. Even though the Model DG-100 Elan sailplanes are not certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29), the actions in this AD are recommended for any of these sailplanes certificated otherwise, i.e., experimental category.
(c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate sailplanes to a location where the requirements of this AD can be accomplished.
(d) An alternative method of compliance or adjustment of the compliance times that provides an equivalent level of safety may be approved by the Manager, Small Airplane Directorate, FAA, 1201 Walnut, suite 900, Kansas City, Missouri 64106. The request should be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Small Airplane Directorate.
NOTE 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Small Airplane Directorate.
(e) The inspection required by this AD shall be done in accordance with the Enclosure to Technical Note 301/15, which is a supplement to Glaser-Dirks Technical Note 301/15, dated July 7, 1989. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from Glaser-Dirks Flugzeugbau GmbH, lm Schollengarten 19-20, 7520 Buchsal 4, Germany. Copies may be inspected at the FAA, Central Region, Office of the Assistant Chief Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri, or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.(f) This amendment becomes effective on August 24, 1995.
